Display Brightness control

0
0

Hello.

 

I've recently purchased a notebook model HP 15-bs018nu, it works quite well, but I have an issue with the display brightness. The issue is, that whenever I boot anything other than Windows or Linux, the display brightness is reset to something dim and I cannot control it. It is so dimm that under daylight conditions it is very difficult to read.

 

I am an OS developer and I often boot and run my own protected mode OS on the machine. I don't have any clue if I can modify my OS so as to change the brightness. Perhaps I should write some values to some ports? Or invoke real mode BIOS some how? From real mode, from protected mode?

 

Perhaps if I upgrade the notebook BIOS I would then be able to control the display brightness from the keyboard?

Or maybe it is stored in CMOS RAM somewhere?

 

 


HP Spectre x360 Vega M VIDEO_TDR_FAILURE (ATIKMPAG.SYS)

0
0

So I've been experiencing a problem ever since I first got my HP Spectre with the Vega M GPU.

 

It comes up with a blue screen, starts collecting data then reboots. The error code is VIDEO_TDR_FAILURE (ATIKMPAG.SYS) which I understand is an issue with an AMD graphics driver.

 

This always happens when the GPU is under a heavy load (usually between 80% - 100% utilisation) running a modern PC game such as GTA V and of course is really frustrating. I tried updating the GPU from Device Manager and there was an update which solved the issue for some games such as Minecraft but still persists for games like GTA V which are a lot more graphically demanding.

 

I then as of 2 days ago started receiving a notification from the AMD Radeon Settings claiming there is a new update for the GPU but once I click it the installer never opens from the settings program even if I have it all set to run as administrator and trying to check for updates in Device Manager says its up to date.

 

I tried downloading the update manually as it lets you if you check the notes but the installer gives me the error message "Error 182 - AMD Installer cannot properly identify the AMD Graphics Hardware. Click here to learn more." which means I can't even seem to update my graphics cards drivers anymore from what it seems.

 

This problem has been a nuisance for the past 2 weeks and I'd really appreciate a professionals guidance in fixing it so I don't have to keep watching my PC reboot randomly during gameplay.

Brightness controls don't work anymore after Windows 10 upgrade

Hello.  I have an older HP ProBook 4420s notebook.  I have recently revived this machine by upgrading to 8GB of RAM (max for this machine), and upgrading to Windows 10 Professional 64-bit.   Everything is running fine and fast.  The only problem that I have found is that some of the function buttons on the top of the keyboard do not work anymore - specifically the Brightness controls (f2 and f3), and the button that toggles between laptop monitor and an external monitor (f4).  I have been to the HP support page for this model, and it does not have any updated drivers for Windows 10.  Does anyone know of a third party driver, or some other compatible driver that will work to get these function buttons to work again?  Is there another work-around to assign specific operations/commands to the individual function buttons?

 

I think the sleep button (f1), the internet button (f6) and the e-mail button (f5) are no longer working either.  :-(

Hello. I have an 8570w running Windows 10. I upgraded the CPU to an I7-3720qm and the graphic to a FirePro M4000. I have an A7E38AA#ABA docking station.  I am trying to get a 4k output to my Vizio m43-c1 4K TV. I purchase a DisplayPort 1.2 to HDMI 4k cable and no luck. Its always showing me only up to 1920x1080 available. I've tried from the dock and from the laptop while removed from the dock. Does anyone have any ideas? Any thoughts or would be much appreciated. Thanks in advance.

the flip to erase functionality of the HP tilt pen has stopped working

my HP tilt pen was working to erase in photoshop and the built in sketch application just fine.  I can't think of anything I did, but flip to erase has stopped working.  When i bring the back of the pen to the screen it's obvious that the API recognizes it as an eraser (photoshop cursor changes to eraser tool) but the screen does not recognize a click when the pen is pressed to it.

The laptop does not detect the second monitor. When I close the lid the second monitors display shuts off.  I want to have the #1 monitor be the main display and the second Monitor be extened from the main display.

Is it even possibel to connect a 2nd monitor which would be #3 sense the laptop screen is #1

Display black, black screen

Hello.

I have a laptop  Compaq Presario CQ56. The problem is that on the screen. It works for a while and suddenly a black screen appeared but not so much black but it looks like a desktop. When I connect a monitor from a PC for this screen I do not think it's a problem in the hardware. Could it be a problem in software? If you can help me, I need a laptop.

Thank you in advance for the answer.

Blue and Purple lined blank screen

Hi, I have left my HP 250 G4 Notebook PC turned on and with the power cable plugged in, I also have an ethernet cable plugged in. I have left it four times now and each time I come back after a few hours it has a blank screen, with thin blue and purple lines running the full length and width of the screen!! If I scroll on the pad it shows a square "but not cursa" in the same colours as the screen, I can not use ctl alt del either and so have to press and hold the power button to switch it off, when I turn it on again it appears to work fine, until it happens again. Only appears to do this when I leave it to idle. Any Ideas, please?  :-)IMG_20180429_124740.jpg

hp spectre x360 15-bl110nd Video Card Selection

0

Hi,

 

My laptop has two video cards, the intel uhd 620 and the nvidia mx 150. It appears as if the intel card is default as it is the one that controls the display settings etc. There is a NVIDIA drop down on right click settings as well but it only appears to have 3D settings.

 

Is there a way to default to the NVIDIA card or is this how the new Specter works where the intel card handles all of the display settings and the NVIDIA is just there to process 3D?

 

Thanks in advance for your help

Hi,

 

I would like to adjust the contrast settings on my hp pavilion laptop. Currently, the contrast settings are only ok when the laptop is plugged in to an electrical socket.  if not, it is almost impossible to see the screen.  I've tried adjusting in control display settings, but there is no menu option for contrast.  

 

any way to adjust this? I haven't had this issue on previous Dell laptops.

 

thanks,

Hi,

 

I am thinking of buying this laptop but I am not sure will I be able to get 4k@60hz on my 32" external display?

atm I use laptop with mDP and I have it but I see that envy doesn't have mDP but type c usb and it says 5gb/s and I believe I need 14+..

 I guess I could only get it work on laptops with mDP or TB3?

My touch screen isn't working

My touch screen isn't working. I know it is a touch screen because the touch screen use to work. The settings says there is no pen or touch available for this display, and there is no HID-Compliant Touch screen, but I know it is a touch screen. When I go to the HP diagnostic touch screen menu the touch screen works. The list of steps it says to do, I've done it over and over again, none of them works. Some of them I have a difficult time understanding. I use my touch screen a lot and find it annoying that it is not working.
